car-sickness的意思|示意

Car sickness，又称为汽车恐惧症，是指乘坐汽车、轮船和飞机时晕车或晕机的现象。它可以表现为头晕、头痛、胃痛、口渴、咳嗽、发烧、出汗、胃痉挛等症状。

Car sickness is usually caused by the discrepancy between the vestibular sensation and visual/kinesthetic sensory input. When people are in a car, the movement of the vehicle is not in line with the vestibular sensation caused by their body movement. The mismatch of the two forces can lead to nausea and dizziness.

In order to prevent car sickness, you should keep the car ventilated and avoid too much acceleration or deceleration. If possible, look out the window and focus on the distant fixed object. Stay calm and relax your mind. If you get car sick, immediately get out of the car and take a few deep breaths to get ventilated air.

In addition, people can take some medicine like Dimenhydrinate, which can help relieve the symptoms of car sickness. It can be taken before getting into the car and should be taken as directed on the package.

Car sickness is really a common phenomenon, so please don't worry too much when experiencing it. But if you often feel sick when riding in a car, it is suggested to visit the doctor and get a checked-up.
